This invention relates to an improved method and means of joining two. metal members together, and more particularly to a means by which to conceal from view such joinder. 7

In its preferred embodiment this invention is directed to the method of oining metal screws to a metal plate in a manner such that.

the screw head is firmly anchored in said 10 plate, being wholly concealed from view as well.

Prior to. this invention, the practise has been to drill openings in a plate, insertrivets in the openings, and, after mounting said plate, headover the rivet ends. Because the rivets are of different composition from the plate in which they are fitted, they react" differently to the air. Consequently, within a short time the rivet heads are of a dif: ferent color from the plateand are m-ostapparent. Furthermore, plates mounted through the use "of rivets tend to become loosened thereby requiring the removal of the old rivets and insertion ofrnew ones.

Another method of providing fastening means on a plate has been to produce lugs which, when formed with threads, may be made tosupport the plate. This practise is objectionable for the reason that lugs, formed from the same composition as the plate, are brittle and break off during manufacture or installation. Often a cracked lug will not be noticed during installation and subsequently the plate will give way as the lug breaks completely 01f.

V The principal object of this invention is not only to avoid the above pointed out objections but to provide a metal plate with" mounting meansv wholly concealed from the face of the plate.

Another object of this invention is to provide plate supporting means which, being formed from a more malleable composition than that of the plate, is of sufficient strength mounting screws to a metal plate in an ab-';

solutely rigid and non-removable manner.

Other and further objects of the invention illustrating the first step of this'process showing the metal rim of the recess in enwill appear froma consideration of the following specification when taken in conjunction with the --accomp-anying drawings, and inwhich 7 I V Fig. 1 is a plan View of one modification of this invention; I z I 2 is a transverse, sectional view showing'the metal plate formed with recesses and Fig. 8 .is a transverse sectional View, show ing screws mounted in the recesses ofthe metal plateand this constiutes the second step in the process; C

U Fig l is a fragmentary s'e'ctional view g agement with and supporting the head of the'screw mounted thereonand this forms the last step in the process; and

' Figs.'5 and 6 are side and end views" of the screw which is' mount'ed on the platellj Referring to-the drawings, Figure 1 shows oiieparticular embodimentof this invention v in the form of a label or card holder-10 havv ing the usual openingill. T Theflanged edge 12,'which extends throughone of the side walls13, permits insertionforremoval' of a card when the holder is mounted for use upon a draweror other receptacle.

1 Centrally of the end walls 14, annular irecesses 15 are formed which are in depth. ap-

proximately two-thirds thejthickness of the card holder 10. Mounted in the recess 15 are screws 16 havingfiat heads 17. As shown in Figure 6 of the drawing, the head 17 is formed with a flat edge 18. The recess 15 is of a diameter sufficient to freely engage the head cess', .When the screwsv are in place (see Figure 3), the walls 19, which constitute the f I rim of the recess, are spun down into close engagement with the screw 16. The recess wall, adjacent the fiat'portion 18 of the screw head, fills in the'space 20 in the recess 15 f adjacent saidhead and prevents turning or Y twisting of the screw. I 7 It has been found in practical use that to mount a malleable screw upon a cast or stamped plate, in the manner above described, provides a plate with a wholly adequate supporting means. For instance, there is no possibility of the screw turningby reason of the flat side 18 of the head of the screw.

Furthermore, the screws-themselves being malleable products, may be considerably abused by twisting or bending without giving 7 way. Should the openings'in the wall, to which the plate is secured, be slightly off center from the screWs,it is not necessary to redrill or enlarge one of the openings since the screws may beslightly bent toovercome the inaccuracy. This method of providing securing means for a plate of this type not' only creates a permanent mounting therefore 4 but is highly economical from the manufacturing standpoint, particularly so in view of the fact that during manufacture the percentage of mutilated orbroken screws is considerably. less than when the screws are formed from lugs integral with the plate.

It may readilybe understoodthat in pro ducing and mounting a plate of this type less time is consumed than is required to produce and mount a plate held in place through the use of rivets. V

While only one modification and one ap plication of this invention has been shown and described, applicant is not limited therer to since it is obvious that other embodiments can be made without departing from the spirit 7 and scope of the invention as set forth in V j the hereunto annexed claims. o r V .Having-thus setlforth my invention what I claim as new and for which I desire protection by Letters Patent is: v

1. The method of permanently joining a a metal screw to a plate, consisting in first,

I forming'an annular recess in one face of said plate; second, flattening one side of the head of said screw; third,'inserting said screw in said recess; and fourth, spinning down the edges of said recess into engagement with the'head of said screw. V

2. The method of permanently joining a metal screw to aplate, consisting in first, 7

forming anannular'recess in one face of said plate; second, flattening one side of the head of said screw; third, insertlng said screw 111 said reces spand fourth, spinning down the edges of said recess into engagement with the head of said screw andalso to occupy the space adjacent the flat side of said screw head.

In testimony whereof I have affixed my signature, f a r V EDWARD H.'ELLISON.
